Abstract: <P>PROBLEM TO BE SOLVED: To provide an apparatus consuming less energy to prevent freezing by draining water in the outdoor piping of a solar heat utilization water heater directly connected to a water supply system.  <P>SOLUTION: In the solar heat utilization water heater directly connected to the water supply system for feeding service water to a hot water tank heated by solar heat from an indoor-side cold water supply pipe via a cold water supply pipe, switching valves A and C are provided. The switching valves A and C enable the cold water supply pipe and a hot water take-out pipe to cut off the communication between the indoor-side cold water supply pipe and an indoor-side hot water take-out pipe for alternately switching to communication with a drain pipe leading to the air. Additionally, a check valve is provided at the inlet of the hot water tank, and an air inflow valve is provided in the cold water supply pipe. The air inflow valve is closed and opened when the cold water supply pipe and the drain pipe cut off and communicate, respectively. Further, an air introduction valve is provided at a position being higher than the hot water surface of the hot water tank of the hot water take-out pipe. In this case, the air introduction valve is closed and opened when the switching valve C makes the hot water take-out pipe and the drain pipe to be disconnected and connected from/to each other, respectively.  <P>COPYRIGHT: (C)2004,JPO
